Hello, Our 13" 2016 MBP is having difficulty with Lightroom 6.10. When in Develop mode, only while cropping, the photo sometimes goes black—for a moment. It is an intermittent issue. This only happens when "Use Graphics Processor" is checked in the Performance tab of LR's settings. Advice from the Adobe LR forum is to toggle off "Use Graphics Processor". While that does prevent the photo from going black, it degrades performance elsewhere in the Develop module. Disappointing. Any thoughts on how to remedy this? I suspect I'm caught between the pointing fingers of Apple and Adobe, each saying it's the others responsibility. Thanks!
